UNITED STTES PATENT OFFICE HIRAM PEAVEY, OF BANGOR, MAINE, ASS IGNOR OF ONE-HALF HIS RIGHT TO MICHAEL SUHWABTZ, OF SAME PLACE.

IMPROVEMENT IN SHlNGLE-MACHINES.

Specification forming part of Letters Patent No. 135,114 l, dated February 4, 1873.

To all Iwhom it may concern:

Be it known that I, HIRAM PEAVEY, of Ban gor, in the county of Penobscot and State of Maine, have invented a new and useful Improved shingle-Machine and I hereby .declare the following to be a full, clear, and exact deseription tlereof, which Will enable others to make and use the same, reference being had to the accompanyin g drawing forming a part of this speeification, in which- Figure shows a front elevation of my invention; Fig. 2, aview of the earriage and cam; Fig. 3, a view of the stop-motion.

Same letters show like parts.

i In my shingle-nachine the carriage is perpendicular and swings upon a shaft at its lower i end. lt receives its motion from a double cam i working in a yoke at right angles, or nearly 'to a larger wheel, e, and to a pinion, f, upon the same shaft, which pinion meshes into a gear, g, upon a shaft, h. Upon this shaft h, at i, is the double cam j, operating the carriage B. A shaft, k, supports the carriage, Which, as before stated, has affixed to it a yoke, l, consisting of arms m n extending above and be low the double cam, one arm, m, being operated by one side, 0, of said cam and the other, a, by the side p, the side o operating to throw the carriage back after the shingle has been cut, rapid] y, and the side 1) bringing the bolt down to the saw more slowly. An adjustable lip, q, is also attached to the cam, as shown, giving it steadiness.

All small bolts are dispensed with and the gears employed have a comparatively slow notion, to avoid breakage. The carriage being perpendicular, or nearly so, its weight is balanced upon the shaftk rather than brought on the yoke and cam, so that the operatingparts of the machine are relieved. Moreover, the saw cuts the bolt lengthwise, instead of slashwisef7 VVha-t I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination of the carriage B, yoke l, and double camj, constructed and operating substantially in the manner shown and before described.

2. The combination with the above of the friction-wheel d and connecting mechanism, substantially as set forth and described.

HIRAM PEAVEY.
